149744-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149744-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,7,4 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 149744-51:
(8*1)+(7*4)+(6*9)+(5*7)+(4*4)+(3*4)+(2*5)+(1*1)=164
164 % 10 = 4
So 149744-51-4 is a valid CAS Registry Number.

SYNTHETIC ANALOGS OF NATURAL FLAVOLIGNANS. II. A NEW SYNTHESIS OF BENZODIOXEPANE ANALOGS OF SILANDRIN AND HYDNOCARPIN
Aitmambetov, A.,Khilya, V. P.
, p. 439 - 442 (2007/10/03)
Benzodioxepane analogs of chalcones have been obtained from which analogs of natural flavolignans - silandrin and hydnocarpin - have been synthesized.The PMR spectra of the new substances are given and are discussed.
